There is a growing interest in the formulations of coating chemical fertilizers with both UI and NI. However, limited information is available on the combined use of UI and NI applied with urea fertilizer. Therefore the aim of this study was to investigate the effects of treating urea with both UI and NI to minimize NH3 volatilization. Two experiments were set up in volatilization chambers under controlled conditions to examine this process. In the first experiment, UR was treated with the urease inhibitor NBPT [N-(n-butyl) thiophosphoric acid triamide] at a rate of 1060\u00a0mg\u00a0kg\u22121 urea and/or with the nitrification inhibitor DCD (dicyandiamide) at rates equivalent to 5 or 10% of the urea N. A randomized experimental design with five treatments and five replicates was used: 1) UR, 2) UR\u00a0+\u00a0NBPT, 3) UR\u00a0+\u00a0DCD 10%, 4) UR\u00a0+\u00a0NBPT\u00a0+\u00a0DCD 5%, and 5) UR\u00a0+\u00a0NBPT\u00a0+\u00a0DCD 10%. The fertilizer treatments were applied to the surface of an acidic Red Latosol soil moistened to 60% of the maximum water retention and placed inside volatilization chambers. Controls chambers were added to allow for NH3 volatilized from unfertilized soil or contained in the air that swept over the soil surface. The second experiment had an additional treatment with surface-applied DCD. The chambers were glass vessels (1.5\u00a0L) fit with air inlet and outlet tubings to allow air to pass over the soil. Ammonia volatilized was swept and carried to a flask containing a boric acid solution to trap the gas and then measured daily by titration with a standardized H2SO4 solution. Continuous measurements were recorded for 19 and 23 days for the first and second experiment, respectively. The soil samples were then analyzed for UR\u2013,       NH   4  +   \u2013    , and       NO   3  \u2212   \u2013  N    . Losses of NH3 by volatilization with unamended UR ranged from 28 to 37% of the applied N, with peak of losses observed the third day after fertilization. NBPT delayed the peak of NH3 losses due to urease inhibition and reduced NH3 volatilization between 54 and 78% when compared with untreated UR. Up to 10 days after the fertilizer application, NH3 losses had not been affected by DCD in the UR or the UR\u00a0+\u00a0NBPT treatments; thereafter, NH3 volatilization tended to decrease, but not when DCD was present. As a consequence, the addition of DCD caused a 5\u201316% increase in NH3 volatilization losses of the fertilizer N applied as UR from both the UR and the UR\u00a0+\u00a0NBPT treatments. Because the effectiveness of NBPT to inhibit soil urease activity was strong only in the first week, it could be concluded that DCD did not affect the action of NBPT but rather, enhanced volatilization losses by maintaining higher soil       NH   4  +      concentration and pH for a longer time. Depending on the combination of factors influencing NH3 volatilization, DCD could even offset the beneficial effect of NBPT in reducing NH3 volatilization losses.", "keywords": ["soil chemistry", "Urease inhibitors", "Surface treatment", "nutrient use efficiency", "Ammonia volatilization", "01 natural sciences", "630", "Ammonia", "Oxidation", "DCD", "Urea", "Urea fertilizers", "Fertilizers", "volatilization", "Groundwater", "0105 earth and related environmental sciences", "soil surface", "coating", "fertilizer application", "Urease inhibitor", "04 agricultural and veterinary sciences", "Nitrification inhibitor", "Nitrification", "Inorganic acids", "6.
